MATTRESS.

Specification of Letters Patent.

Application filed January 18, 1912. Serial No. 671,801.

2 '0 all whom it may concern 1130 it known that I, JOHN L. IIEFFNER, a cit-i cu of the United States, residing at- Peoria, in the county of Peoria and State of 5 lllinois, have invented certain new and use fulimprovements in Mattresses, of which -the following is a specification.

iMy invention relates to mattresses and the like. I

More particularly, my invention relates to meal-isfor forming a mattress that will not "-rteh and that when formed with the up.-

per 'and tufted, aid material will not be nnder lateral tension due to any lack of 'tmiformity in .thetrelative positions of the connecting threads lmtwcwn the top and bottom cover-I ings, thereby producing side walls of the mattressthat will be even, uniform and regi'iilar.

My invention consists in the particular formation of the top and bottom covers of a mattress with a series of folds extending the length and width of the same, each fold being stitched its entire length exccpt at crossing points where the stitches are interrupted to provide fulh'iess to be drawn down into the body of the mattress in titfting. fullness left in the covering permits the top sllrl'acc to he formed in biscuit, diamond or other irregularities of surface, but the stitching prevents the mattress from stretching. 7

Refer ing to the drawings, Figure 1 is a perspective view showing a mattress partially completed; l ig. 2 is a perspective view showing a section of a covering for the mattress either for the top or bottom.

in the drawings, refers generally to a mattress, B to the top covering thcrcof,1he lower covering conforming exactly thereto.

(7 represents the side walls or side covering for the mattress.

When completed, the mattress is designed to be'in box shape and tufted as shown.

Referring particularly to Fig. 2, I will designate the section of mattress covering as D which covering in the ,form shown is adapted for both the bottom and the top of the mattress. In forming the covering, I have designed to so dispose the material that when t-lic lillcr is interposed between the top, bottom and side walls of the mat- Ircss, the biscuit (or diamond shaped, if desired) formation resulting from t-uftiug will be provided for in the material without havlower coverings attached. and

The I .ing to stretch. and produce untied or insccure folds as results in ordinary tufting, which consists merely in passing a looped thread from one covering to the other and drawing the top and bottom walls down into the filler. Again referring to Fig. 2 a refers to transverse folds that cross at the center point b. c are transverse stitched seams describing a gradual curve from one centering point I) to another, gradnall digressing from the edge of folds a from each centering point I) to the middle portion of the scam with an interruption of the stitches at each side of the centering point. Such Interruption of the stitches before reaching the centering points and the gradual approach of the stitches to the outer edge of the folds allows f or a looseucss or surplus of material to be taken up and drawn down into the filler in tufting, thus giving a natural curved contour or biscuit formation to the surface of the mattress.

The top and bottom covering of the mattress are exact duplicates with scams and centering points exactly matching. 0 that when the tiller is in the mattress and in tuftmg the needle is passed from ccliltlillg point.

Patented June 18. 1912.

b ou'either the bottom or top covering, it i .will be passed to its matching centering point on the other side, thus producing an absolute uniformity of thc tul'ting threads which will produce a perfectly square form.

The advantage resulting from the conformity of centering points of the respective top and bottom coverings, as distinguished from the uncertain and irregular passing oi. the tut'ting thread from ouc int-losing sideto the other of a mattress. is that in such irregular lul'ling uucipial strains arc exerted on the incloscd material. which results in drawing the matcrial irregularly in and out at the edges of the mattress. llnicb) producing an irregular surface. when needs to be corrected by take up stitches through the side walls of the Itlnllrcss to the top and bottom coverings.

In forming a mattress by my method, no take up stitch is absolutely nccc:-sar however it maybe added as simply a supplement edge stitlener.

In carrying out the lulting operation. the substantially straight line position of transverse stitching is not changed, as it is the fullness or loos-cures at the centering points that is drawn down into the tiller, and substantially no strain is exerted at the inter kee I desireit understood mediate stitched points nar said centering points. Therefore if the tufting Should break, the relation of the stitches is such that any tendency of the mattress t stretch is resisted, whereas. in ordinary tu fting the mattress/Would spread. .5 By employin my methods ofproviding surplusim'ateria ahthe tufting points an sha ing the material by means of the partlc fiar manner of stitching the folds and matching the top-and bottom cover-in s so as to produce corres ending gen ering points, I'am able to pro, uce a matt resstjhat will not stretch and that will permanently its box form. f; 7

that tuftin 1 may produce the bis uit, diamond or o er I forms upon the surface, also I do not desire within the principle disclosed.

' to limit myself to the exact details of form ing the top and bottom coverings but claim broadly all structures that fall legitimately What'I claim is:

1. In a mattress;'topiand bottom coverings folded at intervals longitudinally and transversely intermediate its sides and ends, each fold being stitched to the covering its entire length except short interrgptions in the stitches at the crossing ints suflicient to provide a fullness adapte to be drawn down 1nto thefiller of the mattress.

2. In a'mattress, top and bottom coverings folded at intervals longitudinally and trans versely, said folds being sewed to ether with short interruptions in the stitc es at the centering points sufiicient to provide a fullness adapted to be drawn 1 down into the filler of the mattress,' said folds bein stitched on a gradually curved line, gra' ually digressing from the edge of the fold from the centering points to. the intermediate point between said centers.

'3. In a mattressf'n top and bottom covering provided with a plurality f-transverse and longitudinal folds intermediate its sides and ends stitched their entire lengths except short interruptions atthe crossing points to rovide tufting centers, said tuftmg centers ing ada ted in 'both' coverin to match exactly, si e walls, and a suitab e filler. In testimony whereof Ihave aifixed my signature in presence of two witnesses.
